Overview
Rockfield Lake (Irish: Loch Pháirc na Carraige) lies on the northern edge of the Irish Midlands, midway between the towns of Carrigallen and Killeshandra and a short drive south of Arvagh. The lake spans roughly 94 acres (38 ha) and reaches a maximum depth of just over 36 ft (11 m) at its southern end. Its surface sits at an elevation of 154 ft (47 m) above sea level.
What makes Rockfield unique is its position on the historic provincial boundary: the western portion of the lake is in County Leitrim (Connacht) while the larger eastern side belongs to County Cavan (Ulster). The Cullies River (“An Abhainn Dubh”) threads through the lake, entering at the south and exiting at the north‑west, linking a chain of smaller loughs – Cullies, Drumhart and Glasshouse – before continuing its journey.
History & Landscape
Until the early seventeenth century the whole of Rockfield Lake was considered part of County Leitrim. The later redrawing of county lines left the lake split between two jurisdictions, a quirk that still appears on modern Ordnance Survey maps (Sheets 27A and 34). The surrounding countryside is a patchwork of townlands: the eastern and north‑eastern shores lie in the townland of Rockfield (also known as Loughnafin) in Cavan, the north‑west in Portlongfield (Cavan), and the south‑west in Aghavore (Leitrim).
A stone bridge – Kilbracken Bridge – carries the R201 (the Killeshandra‑to‑Carrigallen road) over the Cullies River just north‑west of the lake, offering a picturesque viewpoint of the water and the surrounding drumlin landscape. Nearby, the derelict eighteenth‑century Rockfield House crowns a small hill on the north‑eastern shore, its garden walls hinting at a once‑grand estate.
Getting Here
By car – From Carrigallen, follow the R201 north‑west for about 3 mi and turn left onto the L1524 sideroad. The lane leads directly to a modest public car park on the eastern shore. From Killeshandra, travel south on the R201 and take the same L1524 turn. Signage for Rockfield Lake appears on the right after the Kilbracken Bridge.
Public transport – The nearest bus services run to Carrigallen and Killeshandra; from either town a short taxi ride (≈ 5 km) will bring you to the lake entrance.
What to See & Do
Angling
Rockfield Lake is renowned among coarse‑fishing enthusiasts. The lake supports a healthy mix of species, most notably bream, roach, hybrids, tench, pike and perch. Anglers favour the eastern shore, where a surfaced track runs along the water’s edge and leads to a small public car park. The track provides access to about twenty comfortable “swims” – shallow spots ideal for casting.
| Species | Typical Size | Recommended Bait |
|---|---|---|
| Bream | 5–12 lb | Worm, caster, maggot, corn |
| Roach | 1–3 lb | Worm, maggot |
| Tench | 3–8 lb | Worm, corn |
| Pike | 5–20 lb | Large minnows, spinner rigs |
| Perch | 0.5–2 lb | Small spinners |
Most anglers set up a 12‑metre pole with a ground‑bait feeder rod; the lake’s mixed nets of bream and roach have been known to exceed 100 lb in recent seasons. The local tackle shop, Greenville House Tackle in Carrigallen, can supply rods, lines and bait. Phone: 00353 49 433 9938.
Licence – Angling on Rockfield Lake requires a valid Inland Fisheries Ireland licence (please confirm the exact requirement).
The lake also hosts mid‑week angling festivals each September, drawing clubs from across the Midlands for friendly competition.
Walking & Wildlife
Beyond fishing, the lake’s tranquil shoreline is ideal for a leisurely stroll. The public car park on the eastern shore is a convenient launch point for short walks that skirt the water, offering views of the surrounding drumlins, the occasional heron, and the gentle flow of the Cullies River. While there are no formal marked trails, the paved lane from the L1524 sideroad to the car park provides a safe, level route for families and casual walkers.
Seasonal Highlights
- Spring (March–May) – Rising water levels and insect activity make the lake productive for roach and bream.
- Summer – Warm days are perfect for family walks; early mornings still yield good pike action.
- Autumn (September) – The lake’s flagship angling festivals take place, and pike are in prime condition.
- Winter – The lake remains accessible, though fishing activity slows; the quiet scenery is ideal for photography.
Nearby Points of Interest
- Portlongfield Lake & Orange Hall – A tiny lake just north of Rockfield, separated by a low hillock, with an historic Orange Hall (c. 1890) nearby.
- Drumhart Lake – A short distance south, another link in the Cullies River chain, offering quieter waters for those seeking solitude.
- Kilbracken Bridge – The stone bridge on the R201 gives a classic Irish countryside photo opportunity.
- Annagh Lake – A larger lake a few kilometres east, popular for swimming, angling and a historic crannóg.
Practical Information
Access – The easiest public entry is via the L1524 sideroad in County Cavan. This road runs close to the eastern shore and connects the townland of Portlongfield with Arvagh. A short paved lane leads from the road to a modest public car park on the lake’s edge. Signage appears on the main Carrigallen‑to‑Killeshandra route (R201) about three miles from Carrigallen; the lake is sign‑posted on the right.
Parking – Parking is free in the on‑site car park. The space is limited but sufficient for a few cars and a small trailer, making it convenient for anglers and walkers alike.
Facilities – There are no built‑in toilets or cafés at the lake; visitors typically use facilities in Carrigallen or Killeshandra, both a few kilometres away. The surfaced track along the shore provides a stable footing for casting and for children to explore safely.
Contact – For fishing enquiries, equipment or local advice, contact Greenville House Tackle, Carrigallen (tel: 00353 49 433 9938).
Season – The lake is accessible year‑round. Angling activity peaks in the spring and early autumn, especially during the September festivals.
Navigation – GPS coordinates approximate the centre of the lake at 53.9500° N, 7.6000° W (latitude 53.95, longitude ‑7.60). These can be entered into any navigation device to locate the public car park.
